About the genus

Teucrium is a cosmopolitan genus of flowering plants in the mint family Lamiaceae, commonly known as germanders. Plants in this genus are perennial herbs or shrubs, with branches that are more or less square in cross-section, leaves arranged in opposite pairs, and flowers arranged in thyrses, the corolla with mostly white to cream-coloured, lobed petals.

In the garden

Teucrium Ackermannii Hort belongs to the genus Teucrium, a group of perennial herbs and shrubs found across a wide range of regions. The plant's corolla is formed of five lobes creating a two-lipped flower, with the upper lip generally reduced and the lower lip divided into three lobes; four stamens are borne close to the petal base and the flowers are presented in clustered inflorescences. Flowering takes place from June to September, providing a clear summer display. When managing plants of this type, check stem and leaf structure to assess vigour and remove spent flowers to keep the display tidy through the season. Light pruning after the flowering period will encourage renewed growth and help maintain a defined shape without heavy intervention. Given the plant’s floral form and seasonal timing, monitor flowering stems for any diseased or damaged shoots and cut these away to promote healthy regrowth. In garden use, the white-to-cream, two-lipped blooms are most effective where the summer display can be seen close to paths or seating. The clear June–September flowering window makes it straightforward to plan companion plants that either precede or follow the bloom period.
